SafetyNet/Play Integrity: Google’s security mechanisms often detect the unlocked bootloader. While the ROM may be "verified" by developers to be malware-free, banking apps may refuse to launch. This requires the use of Magisk (a root hiding tool) to pass the SafetyNet check.
OTA Updates: Custom ROMs do not support seamless Over-The-Air (OTA) updates in the same manner as stock Fire OS. Users must manually flash new updates, which carries a risk of data loss if not performed correctly.
The "Brick" Risk: Because the bootloader is hacked rather than officially unlocked, flashing certain partitions (like the Preloader) can permanently "brick" the device, rendering it unrecoverable without advanced hardware tools (JTAG/EDL cables).
